IMPROVEMENT IN FEED-WATER DEVICES FOR BOILERS.

The Schedule referred to Iin these Letters Patent and making put of the lam.-

To all whom Iit may concern Be it known that I, JOHN D. OTIS, of the city of Peoria, in the county of Peoria, and State of Illinois, have invented a new and improved Mode of Regulating the Supply of Water in Steam-Boilers, to obviate the dangers of explosion, and all other diiicnlties that may arise by th'ere being too much or too little Water; (the principal object is to regulate the flow of water to a steady gauge and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure 1. Letter A represents a steam-boiler.

Letter B represei'lts a water-tank.

Letter C represents a force-pump, with pipes con `uected with valves in Water-tank and boiler.

Figure 2. Letters P, w w, and r 1', represent the valve and valve-seat. i

q, the V-openings, of which there are three, that the water 'has to pass through to vthe heater or pump, through pipe'S.

J J is a cap, or bonnet, that covers the valve P, and

protects it from all sticks or. stones that might" acci-A dentall'y get in the ltank B. It also forms a strainer,

being perforated with three or four rows of small holes 0n upper end of pipe C 'there is a stuffing-box, j, to pack rod a.

The lower end of pipe G is long enough to reach into the Water iu the boiler, so as to carry a column of water up in pipe G, and around rod a, to the packing in stung-box f, so as to keep the packing iee and moist, and clear off the hot steam.

b is au arm that is fastened to pipe C by means of set-screw, the lower end of arm supporting lever u.

t represents the oat that is attached to the end of w w, the valve-seat, which is square, and a ground I joint, so that when the valve is closed it forms a perfectly-tightjo'iht, and shuts the Water entirely oif.l

What I claim as my invention, and desire to secure by Letters Patent, is-

l. -The regulating feed-valve P, in combination with the seat 'w fw, guide 'r fr, and cap J, substantially as set forth.

2. The lubricating Water-pipe c, with the stutlngbox f, constructed substantially as set forth.

3. The arrangement of the oat t, arms n and b, the rod a, pipe c, and stuffing-box f, rods h and k, support t', rods l, m, n, and o, and valve P, substantially as hereinspecied.

JOHN D. OTIS.
